Security-Enhanced Linux secures the boinc processes via flexible mandatory access control.
You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux boinc policy is very flexible allowing users to setup their boinc processes in as secure a method as possible.
The following file types are defined for boinc:
boinc_exec_t
- Set files with the boinc_exec_t type, if you want to transition an executable to the boinc_t domain.
boinc_initrc_exec_t
- Set files with the boinc_initrc_exec_t type, if you want to transition an executable to the boinc_initrc_t domain.
boinc_log_t
- Set files with the boinc_log_t type, if you want to treat the data as boinc log data, usually stored under the /var/log directory.
boinc_project_tmp_t
- Set files with the boinc_project_tmp_t type, if you want to store boinc project temporary files in the /tmp directories.
boinc_project_var_lib_t
- Set files with the boinc_project_var_lib_t type, if you want to store the boinc project files under the /var/lib directory.
boinc_tmp_t
- Set files with the boinc_tmp_t type, if you want to store boinc temporary files in the /tmp directories.
boinc_tmpfs_t
- Set files with the boinc_tmpfs_t type, if you want to store boinc files on a tmpfs file system.
boinc_unit_file_t
- Set files with the boinc_unit_file_t type, if you want to treat the files as boinc unit content.
boinc_var_lib_t
- Set files with the boinc_var_lib_t type, if you want to store the boinc files under the /var/lib directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux boinc policy is very flexible allowing users to setup their boinc processes in as secure a method as possible.
The following port types are defined for boinc:
Default Defined Ports: tcp 1043
Default Defined Ports: tcp 31416
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux boinc policy is very flexible allowing users to setup their boinc processes in as secure a method as possible.
The following process types are defined for boinc:
boinc_t, boinc_project_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.
The SELinux user type boinc_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
boinc_log_t
/var/log/boinc.log.*
boinc_project_var_lib_t
/var/lib/boinc/slots(/.*)?
/var/lib/boinc/projects(/.*)?
